📋 When to Use 12-Character Passwords

12 characters is the recommended minimum for most online accounts. With all character types, it takes years to crack. This is the sweet spot between security and usability — suitable for social media, shopping, and most everyday accounts. NIST recommends at least 12 characters for machine-generated passwords.

📊 Technical Breakdown — 12-character

  • Entropy: 68 bits (full) / 57 bits (letters+digits)
  • Crack time: ~3,000 years (GPU cluster)
  • Security level: Good
  • Best for: Web accounts, social media, work

All calculations assume 12-character with mixed character types. Actual security depends on specific character selection.
